PRESSER ATTACHMENT FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 347,254, dated August 10, i886.

Applicalioirfili-d April 15, 1886.

To all whom it may concern.-

Be it known that I, GEORGE W. PASSEL, a citizen'of the United States, residing at Cincinnati, in the county ofIIamilton and State of Ohio, have invented certain new and use ful Improvements in Presser Attachments for Planing-ll/Iachines; and I do hereby declare the following to be a full, clear,.and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that type of presser attachments for planing-machinesin which the presser acting on the board in advance of the planing-cylinder-the fore presser con- Sists of a hinged yoke suspended by its arms, on which it is horizontally adjustable from the bearings of the planing-cylinder, and an inclependently-adjustable presser-foot, which has also a limited independent up-and-down motion on the yoke.

My improvementconsists in mounting theindependently adjustable and movable presserfoot on curved guides, the curvature of which is approximately concentric with theplaningcylinder.

Figure 1 represents an end elevation of my improved presser attachment, showing also the planing-cylinder and some other parts to clearly illustrate the application of the att-aclr ment. Fig. 2 represents a plan view of the same. Fig. 3 represents a side elevation of the fore presser, showing that side which faces the planing-cylinder. Fig. 4 represents a side elevation of the after presser, showing that side which faces the planing-cylinder. 5 represents a top View of the fore presserfoot. Fig. 6 represents an end view of the fore presser-foot. Fig. 7 represents a top View of one of the curved guides. Fig. 8 represents a side view of one of the curved guides.

The same letters of reference indicate identical parts in all the figures.

The fore presser consists of a hinged yoke and the presser-foot- B. The bar A of the hinged yoke has arms A A, by which it is hinged to or suspended from lugs e on the bearings E of the planing-cylinder. The bar Aof the yoke is bolted to its arms through Fig.

bar A with reference to the planing-cylinder. The bar A of the yoke is provided with guide-blocks A A having curved grooves, which are engaged by eorrespondiugly-curved tongues B B on the respective ends of the presser foot B. The presser foot and its tongues and the grooves in the guideblocks of the yoke are so curved as to be approximately concentric with the planingcylinder, all but the upper portion of the presser-foot, which is shaped to recede from the planingcylinder. as usual. Thepresser-foot has lugs b b projecting over the top of the guide-blocks of the hinged yoke, and screwed through these lugs are set-screws b" b, which, by striking the top of the guide-blocks, limit the descent of the presser-foot on the yoke. The rise of the presser-foot on the yoke is limited by a set-screw, a, in a lug, a, on the bar A of the yoke, which set-screw is struck when the presser-foot rises a determined height by a lug, I)", on said presserfoot. On being forced up still higher the presser-foot and yoke rise together.

The presser-foot may be somewhat loosely fitted in its guides, so that it may accommodate itself readily to inequalities crosswise of the board.

It is expedient to construct the guide-blocks of separate pieces, and bolt them to the yokebar, as shown; but that is not essential by any means.

' The after presser is constructed and mounted after the ordinary manner, as shown in the drawings.

I am aware that it is old to mount presserfeet on curved guides; also, that it is old to mount an independently adjustable and movable presser-foot on straight guides on a horizontally-adj ustable bar of a hinged yoke; but 0 By this construction I am able to adjust the 5 fore presser close to the cut,irrespective of the rise of the planing-cylinder and the depth of the cut.

I claim as my'invention' In testimony whereof I affix my signatm'ein A fol-e presser for planing-machines, subpresence of two witnesses. stantially as before set forth, consisting of a l 7' 1 hinged yoke constructed with a horizontally- GEORGE 1 ASSET 5 adjustable bar and an independently adjust- \Vitnesses:
